Airtac SAIF Series Standard Cylinder with Valve SAIF80X250S-10B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X250S-10B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 250mm stroke and a built-in 4M310-10 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.

About the Airtac SAIF Series Standard Cylinder with Valve SAIF80X250S-10B
The AirTAC SAIF80X250S-10B is a double-acting ISO 15552 profile cylinder featuring a built-in 4M310-10 5/2 solenoid valve. This integrated manifold uses O10 x O6.5 PU tubing to connect the valve block to the 3/8 cylinder ports, eliminating remote plumbing. Driven by a DC24V terminal coil drawing 3.0 W with an IP65 rating and 0.05 s response, it delivers 2513 N push force at 0.5 MPa. Because the 5/2 valve operates at 0.15-0.8 MPa, this defines the practical working range for the assembled unit, even though the bare cylinder rates to 1.0 MPa.
Factory-set to retract the rod when the coil is energised, the valve can be repositioned to extend on signal. The -S magnet supports CMSE reed and DMSE electronic sensors for position feedback. By switching itself from one coil signal, this self-contained unit saves panel space and is ideal for decentralized stations across large machines.

| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
Sized within the valve's 0.15–0.8 MPa range. Actual usable force is lower than theoretical due to friction and back-pressure.

SAIF does not hold its load without air — the valve routes air, it is not a lock. For load-holding use a SAIL (lock) or BSAI (clamp-lock).
Where the Airtac SAIF Series Standard Cylinder with Valve SAIF80X250S-10B Is Used
Decentralized Machine Stations
Eliminates the need for a remote valve island on large assembly lines, driving heavy 2513 N push loads directly from a single DC24V signal.
High-Force Clamping Fixtures
Provides robust clamping via the 80 mm bore, with the built-in 4M310 valve ensuring rapid 4 cycle/sec actuation without complex air plumbing.
Retrofit Automation Upgrades
Ideal for upgrading existing ISO 15552 mounts where adding dedicated valve tubing is difficult, offering a self-switching terminal-wired solution.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X250S-10B the Right Choice?
Choose this 80 mm bore when you need substantial thrust (2513 N push at 0.5 MPa) without stepping up to the 100 mm bore (3927 N). The integrated 4M310-10 valve offers a 30.0 mm2 effective area (Cv 1.68) and handles up to 4 cycles per second, making it highly effective for heavier decentralized actuation where running separate valve tubing would be costly. At 250 mm stroke, ensure adequate guide support to prevent side-load wear on the rod and cylinder seals. The carbon steel rod and PT tapered threads are standard.
Remember the built-in 5/2 valve routes air but does not lock the load mechanically; for position holding under load loss, consider an AirTAC SAIL lock cylinder. To replace this unit, match the 80 mm bore, 250 mm stroke, 3/8 valve port, DC24V voltage, terminal entry, and -S magnet.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → SAIL / BSAI
Airtac SAIF Series Standard Cylinder with Valve SAIF80X250S-10B FAQ
At 0.5 MPa, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. The integrated 4M310-10 5/2 valve has a 30.0 mm2 effective orifice area (Cv 1.68) for high flow.
No, the SAIF80X250S-10B has a 4M310 valve built into its manifold. It operates directly from a DC24V terminal coil. By default, the rod retracts when energised, but you can reposition the valve to extend on signal.
